Abstract

LOS EJES DE TRES VALVULAS DE ENTRADA (5, 6, 7) ASOCIADOS CON CADA CILINDRO DE UN MOTOR DE COMBUSTION INTERNA SON PARALELOS ENTRE SI. LAS VALVULAS FUNCIONAN TODAS MEDIANTE EL MISMO ARBOL DE LEVAS (8), QUE ACTUA SOBRE LAS TRES VALVULAS DESDE ENCIMA, A TRAVES DE TRES BALANCINES (9) EMPUJA-VALVULAS INTERPUESTOS. EL BALANCIN (9) DE LA VALVULA (7), QUE ESTA EN LA POSICION INTERMEDIA, ESTA EN ORIENTACION INVERTIDA RESPECTO A LOS OTROS DOS BALANCINES (9).
